3 RE 86-4/6. KKDE Hydraulics Bosch Rexroth AG / Function, section, symbols General The / directional spool valves are direct operated, pressure-compensated cartridge valves. They control the start, stop and direction of a flow and basically comprise a housing () with a movably mounted socket (), the control spool (5)and a return spring (4). Function In the de-energized condition, the control spool (5) is held in the initial position by the return spring (4). The control spool (5) is actuated by wet-pin DC solenoids (). The symbols are realized by different spools (C or U). The main ports,, and are suitable for a continuous load with an operating pressure of 5 bar and the flow can be directed into both directions (see symbols). The manual override (6) allows for the switching of the valve without solenoid energization. It is also available in screwable version "N" (7) (see page ).

For more information and data on the use of other hydraulic fluids refer to data sheet 9 or contact us! There may be limitations regarding the technical valve data (temperature, pressure range, service life, maintenance intervals, etc.)! The flash point of the process and operating medium used must be 4 K higher than the maximum solenoid surface temperature. Flame-resistant water-containing: Maximum pressure differential per control edge 75 bar, otherwise, increased cavitation erosion! Tank pre-loading < bar or > % of the pressure differential. The pressure peaks should not exceed the maximum operating pressures! Environmentally compatible: When using environmentally compatible hydraulic fluids that are simultaneously zinc-solving, zinc may accumulate in the medium (7 mg zinc per pole tube). ) The cleanliness classes specified for the components must be adhered to in hydraulic systems. Effective filtration prevents faults and at the same time increases the service life of the components. For the selection of the filters see
